NEET2005PhysicsMotion in One DimensionActual
The displacement x of a particle varies with time t as x=a e^ -a t +B^ x , where a, b, and are positive constants. The velocity of the particle will:
Options
- Abe independent of
- Bdrop to zero when =
- Cgo on decreasing with time
- Dgo on increasing with time
Correct answer
D. go on increasing with time
Step-by-step solution
From question aligned & x=a e^ - t +b e^ t & V= d x d t =-a e^ -x t +b _e^ B + & V =-a e^ -t +b ^ t aligned Velocity will decrease for certain value of t .
